I had an earlier thread about picking a contractor and got great advice from the team here.
I have now gotten 3 different estimates, and these estimates vary a bit. There are 2 Trane and 1 carrier estimates all are from long term local companies and I feel they are all reliable. One of the carrier and one of the trane estimates are nearly identical cost wise. One of the trane esimates is 40% higher than the other 2.
Since this is a zoning system, with heat only (we live in an area that does not require air conditioning) and the zoning control and performance is the most important part of the deal to us I had some questions.
It appears that both of the Trane estimates include different zone system vendors, does Trane make a zoning system of their own?
The carrier guy told me that the infinity system is the best on the market if you want automatic zone control. Both of the trane guys were quoting third party zoning systems (one honeywell, one white-rodgers). The Carrier guy kept telling me how advanced the infinity system is given that it is infiniately adjustable compared to the honeywell and others that were not. With a zone system is a load calc different?
Is the Infinity zone system that much better than the others mentioned? Everything else seems to be similar. I am goiing with 2 speed, 90+ efficiency units.
anything else that I am missing?
I did get into contact with a local installer who frequents these boards, but he was too far away (with traffic) for the deal to make sense.
